The PCMCIA ioctl -- deprecated for years -- suffers from insufficient
locking. As it already has been deprecated for years, with its removal
long overdue, limit it to !SMP and !PREEMPT.

Furthermore, the last legitimate use of the ioctl to be reported
relates to the ARM architecture in 2008.[1] Attempts to resolve
this issue turned out unsuccessful so far.[2] Other usages have only
been reported as hear-say. If there are any legitiate and necessary
use-cases remaining, please speak out before the end of the grace
period until 2.6.3{5,6}(-rc1).

New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000),
which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c.
Notable improvements:
        - supports Db1000, DB/PB1100/1500/1550/1200.
        - support for carddetect and statuschange IRQs.
        - pcmcia socket mem/io/attr areas and irqs passed through
          platform resource information.
        - doesn't freeze system during card insertion/ejection like
          the one it replaces.
        - boardtype is automatically detected using BCSR ID register.

Run-tested on the DB1200.

This is because

The socket driver m8xx_pcmcia.c uses a static memory assignment,
but io_offset is set to 0. Therefore, it seems proper to use the
iodyn resource manager for this driver, as was previously the
case (before commit 80128ff7).

m32r_cfc sets the socket capabilities to SS_CAP_STATIC_MAP and
also sets io_offset != 0. This means no calls to
&pccard_nonstatic_ops went through. Therfore, replace it with
&pccard_static_ops which is exactly for this case.

Adds support for PowerQuicc on-chip PCMCIA.  The driver is implemented as
of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.

To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.

Some PCMCIA sockets have statically mapped memory windows, but dynamically
mapped IO windows. Using the "nonstatic" socket library is inpractical for
them, as they do neither need a resource database (as we can trust the
kernel resource database on m68k and ppc) nor lots of other features of that
library. Let them get a small "iodyn" socket library (105 lines of code)
instead.

addressing comments by Jeff and Dominik:

- use IO accessors instead of direct device memory referencing
- avoid usage of non-standard "uint/uchar" data types
- kill struct typedef's

Will submit it for inclusion once v2.6.14 is out.

Testing on 8xx platforms is more than welcome! Works like a charm
